Fast handover in mobile communications networks

摘要

A mobile node apparatus is described for routing of data in hierarchical mobility management systems with tiered mobile anchor points. Routing of data is switched from old to new communications nodes by a controlling mobile anchor point having both communications nodes in its domain. This switching is regulated to occur synchronously with the expiry of a determined period following its receipt of a handover initiation signal. A determinant of the period is a remaining time of attachment of the old communications node.
